Either fail or support multiple targets

See gohugoio/hugo#3939

Good thing I tested.

So I just replaced make with mage and got:

mage hugoRace check

Wich does not fail. If you do not support multiple targets you really should exit with error + some error message.

So, the idea is that a target may want to process arguments itself. Right now you can have a target get os.Args and read off the second argument you give it.

There's a couple issues on this - #24 #34

See the discussion on #34 especially.

I agree that it is suboptimal as-is. Maybe an interim solution is to default to disallowing extra args, but have an opt-in variable you can set to say you want to process extra args yourself.

like

var ArgPassthrough = true

I agree that it is suboptimal as-is.

That isn't the word I would use. Having people moving from make to mage and think that their build is "green" when it's not, is everything a build system should not be about.

I think you should move extra args to a --args flag or something.

I'll make a PR to have mage fail with multiple args until we can flesh out how to run multiple targets in a sane way.
